1 Claim. (Cl. 933-391) This invention relates to a structurally and suming that the shaft l2 and mandrel II are functionally improved receptacle as well as a power driven, it follows that with the web propmethod of forming the same. erly applied to the mandrel, a multi-ply body will It is *an object of the invention to furnish a be built up on the latter. The paper may, of receptacle which will embody a construction such course, be formed of any convenient stockand that a permanent interlock will be provided bebe impregnated with any suitable and desired tween the body and end wall thereof, such insubstance. Additionally, a film of material may terlock satisfactorily resisting any stripping acbe'applied to the web so that all layers are adtion to which the receptacle might normally be hesively or otherwise secured to each other and subjected in usage. against any possibility of accidental movement.

As such, there is provided by the present in- I have heretofore proposed to seal the ends of vention a receptacle, the body of which may be a receptacle such as this by, for example, emformed of paper or similar material, and the end ploying an end member which, in the case of wall or walls of which may be furnished by metal being applied to a tubular receptacle body (as closures, these closures and side walls furnishing shown in the drawing), should likewise be of in aggregate a container capable of receiving circular outline and of a diameter substantially fluids or other material to be packaged, and equal to the receptacle end. This end seal may maintaining such material in proper condition include a wall- It having an outwardly and infor substantially indefinite periods of time. wardly extending flange portion ll which will Another object is that of teaching a method thus be generally U-shaped in cross-section. whereby a receptacle of this character may be While not essential, it is preferred that this flange furnished;-and.which method may be practiced portion have its outer arm of a length or height by relatively unskilled persons to provide an less than the inner arm of such flange portion. article which may be placed upon the market Also, while the inner arm should preferably be I at a nominal figure. uninterrupted or plane to have its face lie in in- 25 With these and other objects in mind, refer timate contact with the inner face of. the recepence is had to the attached sheet of drawings iltacle body, the outer arm preferably presents lustrating one practical embodiment of the inboth an inwardly crimped portion l8 as well as a 3o ,vention, and inwhich: rolled edge l9. Thus, as the crimp is formed or Fig. l is a somewhat diagrammatic side elevaspun into the outer end of the end-seal flange, or tion of a forming machine; as such outer end or arm is folded inwardly Fig; 2 is a fragmentary plan view of the parts against the outer face of the receptacle body, the as shown in Fig. 1; layers 20 of such body are urged or compressed 5 Fig. 3 is an enlarged fragmentary view showing inwardly as indicated at 2|. This will, of course,

Likewise, the rolled edge portion l9 Fig. 4 is an enlarged. sectional view taken will engage the outer surface of the receptacle through the top of a complete receptacle, and body to prevent withdrawal of the receptacle from 40 Fig. 5 is a side elevation of such a complete the end seal. In certain instances, and due to receptacle with certain of the parts broken away severe usage, the intimacy of interlock between to disclose underlying construction. the rolled edge or bead l9 and the receptacle wall Referring primarily to Figs. 1 to 3, the numeral has been insuflicient to prevent all possibility of H) indicates amachine deck upon which a manaccidental-withdrawal of the end seal. drel II is rotatably mounted as, for example, by It is proposed, by means of the present invena shaft l2 supported in bearings l3. This mantion, to overcome this objection by associating, drel may be of the collapsible type or any other for example, with mandrel II a pair of indenting desired construction may be furnished which will rollers or discs 22, which may form a part of 9. allow for a ready stripping of formed material main roller 23. 'These discs are pressed into 56 from the body of such mandrel. intimate contact with the face of the mandrel, for According to the present invention a recepexample, by means of a spring 24, which bears tacle is to be furnished which comprises a pluagainst the levers supporting cylinder'23. .These rality of paper layers. To this end a web ll levers indicated at 25 may, of course, be deliberextends from a source of supply (not shown) and ately rocked by an actuating rod or rods 26. Also, which web may be periodically severed as, for while cylinder 23 may move in any desired manexample, by a shearing mechanism l5. Thus, asner, it is preferred that it depend upon the frictional contact between the. discs or rollers 22 and the surface of the receptacle.

As a consequence of this construction it will be understood that as the receptacle body is built up upon the mandrel II and as shown in Fig. 1, the cylinder or roller 23 will firmly press against the outer face of the outer convolution appearing upon such mandrel. Simultaneously, the roller or discs 22 will exert a crimping or indenting action such that as illustrated in Figs. 3 and 4, a groove 21 will be formed in the outer face of the receptacle. The groove will be in linewith the bead I9 when the parts are in proper position.

It is therefore obvious that with the bead or rolled edge portion pressed inwardly as indicated 'in Figs. 4' and 5, it will enter the'groove fl and,-

in effect, interlock against movement with respect to the receptacle.

Thus, at the time of formation of the latter, a preformed groove is provided and this will function in a manner such that there will be no likelihood of the end seal being displaced, regardless" 25,, j Thus, among others, the several objects of the sive action whereby to form a groove in such outerface, continuing such compressive action throughout such area while disposing one. ply

after another upon-the initial layer of said web to furnish a tubular receptacle of multiply construction and each ply of which is formed with a grooved area of substantially the same width as those which are formed in adjacent plies, such grooved areas being continuous and nested one within the other in the complete receptacle, and said complete receptacle presenting an ungrooved inner face and an inwardly grooved outer face.
